Kurzfassung englisch:
We investigate the loss of stability of the steady configuration of
a planar visco-elastic belt drive. The belt is considered as a
linearly visco-elastic slender beam with small bending stiffness,
which is driven by a steadily rotating drum. Due to the presence of
the small damping parameter and the small bending stiffness, the
equations of motion are severly singularly perturbed. By variation
of system parameters, like the driving speed, the damping
coefficient, the tension force and the radius of the drums, we
calculate the steady configuration and the stability limit of the
belt. Our calculations show, that the viscous damping, the
distributed load
and the strong bending at the drums can decrease the critical
driving speed significantly and lead to flutter oscillations.
